Question 20: A transformation method which may cause the change in a shape of an object is referred as, Translation is an efficient transformation method in which an object may shift form one coordinate position to any other coordinate position in a three-dimensional plane. Question 19: An efficient transformation method in which an object may shift form one coordinate position to any other coordinate position in a three-dimensional plane. Question 18: An efficient transformation method which produces a parallel mirror image of an object is also referred as,Īn efficient transformation method which produces a parallel mirror image of an object is also referred as reflection. Question 17: A line segment of a polygon may also be referred as,Ī line segment of a polygon may also be referred as Edges. Other transformations include reflection and shear, which are simple geometric transformations. Question 16: The fundamental geometric transformations are as follows: To scale a polygon, multiply the product of each vertex's (x, y) by the scaling factor sx and sy to get the transformation coordinates. Question 15: We set all scale factors to reduce the object's dimension. Question 14: Which of the following is a matrix form of 2D translation equation is,Ī matrix form of 2D translation equation is P'=R*P. Question 13: The transformation of the entity in relation to an axis is called the reflection image.Ī transformation that creates a mirror image of an entity relative to an axis of reflection is called a reflection. Question 12: A two-dimensional point is transformed by inserting.īy inserting localization distances dx and dy we can convert 2D points. Transformations are another name for colour mapping functions.
Question 11: The transformation set is also known as, The translation vector or shift vector is described as the distances (dx, dy) from the original location. Question 10: The distances between two points (dx, dy) are referred to as translation distances (dx, dy).Īnswer: a. In order to rotate an object, we must specify the position of its pivot or pivot angle, either the rotation point or its height, or the magnitude of the rotation, and an angle relative to the pivot. Question 9: What is a necessary to specify to generate rotation? Question 8: The colour transformation is performed in the centre of the process_Ī single colour model is a colour transformation process. Translation is a deformation-free rigid body transformation that transfers objects. Question 7: _ is a rigid body transformation that enables an entity to shift without deforming. Repositioning it along with straight line pathĪn entity is converted as it is repositioned in a straight-line path from one spot to another. Repositioning it along with straight line pathĪnswer: b. It's being repositioned around a circle lane Question 6: The term "transformation" refers to the process of applying a translation to an entity. In scaling, we just enlarge or diminish the size of the object without interfering with its shape. In rotation, the object is rotated as it is according to the required angle of rotation. In translation, we just move the object from one place to another. The Shape of the object does not get deformed in any of the transformation techniques: translation, rotation or scaling. "In all these three transformation types, the shape of the object is never deformed."
They are: Translation, Rotation and Scaling."īased upon the above statement, determine whether the following condition is true or false. Question 5: "There are three basic transformation techniques in Computer Graphics to alter an object. The scaling factor determines whether the size of the object is to be increased or decreased. Scaling subjects to the co-ordinate points of the original object is to be changed. Scaling is be used to increase or decrease which is reduce the size of object. Question 4: Which of the following transformation techniques is responsible for altering (either enlarging it or diminishing it) the size of the object? The positive value of the rotation angle rotates an object in an anti-clockwise direction while the negative value of the rotation angle rotates an object in a clockwise direction. Question 3: What value of the rotation angle rotates the object in clockwise direction? The translation pair (Tx, Ty) is called as the shift vector. What is another name for the Translation pair (Tx, Ty)?
The movement of objects without deforming the shape of object is called Translation. Question 1: In which of the following transformation methods of Computer Graphics is the Shape of the Object not deformed? The resolution of random scan is higher as compare to raster scan.
